This is How Sigma Makes The World's Smallest Full Frame Camera

The Sigma fp and fp L cameras, recognized as the world's smallest and lightest full frame interchangeable lens cameras, are products of Sigma's meticulous design and manufacturing process. A recent video reveals the detailed behind-the-scenes of how Sigma designs, machines, and assembles these cameras.

The Sigma fp features a 24.6-megapixel full frame image sensor, whereas the fp L is equipped with a 61-megapixel sensor. Both models share the same body design, with the primary difference lying in the sensor and the resulting specifications due to the resolution difference.

Creating such advanced cameras involves years of careful design, planning, and innovative engineering. As camera technology progresses, the demands on engineers increase, especially for features that offer more sophistication.

The production of these cameras is a complex process. After finalizing the specifications and required parts, each component undergoes rigorous testing. This includes precise 3D measurements of the body and internal chassis. Expert assembly follows the testing phase.

Sigma's meticulous attention to detail is evident in every step, from printing and painting information on the camera’s exterior panels to testing ports, calibrating the image sensor and focal plane, testing the lens mount, verifying firmware, and more.

The Sigma fp and fp L are designed with a modular approach, and this extends to optional accessories such as the add-on electronic viewfinder, which Sigma employees also build and test.

While the Sigma fp L is priced at $2,500 for the body and $3,000 for the kit with the EVF-11 electronic viewfinder, the more affordable Sigma fp retails for about $1,500. The pricing reflects the complexity and advanced technology of these cameras.

I had an FP for a year or so, it was lovely to use but the AF was comically inept. The 45/2.8 kit lens was absolutely superb, the 65/2 less so. I’d love to have tried the 90/2.8. My favourite lens by far, because it got around the failings of the AF system and made the most of the camera’s small form factor, was the FunLeader 18mm f8 fixed focus, fixed aperture lens. If I had the spare cash, I’d get an FP L with the FunLeader just to carry in my pocket.
